foxnews.com — The 102-story building routinely lights up its famous spire to honor everything from traditional holidays to sporting events to notable charities to "the myriad ethnic groups living in the New York City area," according to the building's website.

But Thursday night marked the first time the all-green lighting was used to mark the kickoff of Eid-al-Fitr, a three-day celebration for Muslims around the world.

The all-green lighting was used earlier in the week to promote the city's Parks Department.

Not many religious holidays make the cut. Green and red are used every year to mark the Christmas holiday season, and blue and white - the colors of the Israeli flag - are used for the Jewish holiday of Hanukkah.
